The AC Spec That Sells Comfort — and Buys You Headaches

Selecting HVAC equipment based only on nameplate tonnage, rather than verified building load calculations, often leads to performance issues. Systems that are oversized for the actual load can short cycle, struggle to control humidity, and create inconsistent indoor conditions. Over time, this can increase energy use and reduce equipment life.

At PSE Designs, mechanical systems are designed using detailed load calculations that reflect occupancy, ventilation requirements, building envelope characteristics, and operating schedules. This ensures heating and cooling capacity aligns with how the space is truly used, supporting stable comfort and efficient performance.

Our Mechanical Engineering Expertise Includes:

• Load-Based HVAC Design: Heating and cooling systems sized using established calculation methods to match real building demand.

• Ventilation Planning: Outdoor air and airflow strategies developed to support indoor air quality and moisture control in accordance with applicable codes.

• New Construction and System Upgrades: Coordinated mechanical designs that integrate with architectural, structural, and electrical systems.

From concept through construction, our mechanical engineering services focus on systems that are code-compliant, efficient, and built for dependable long-term operation.
